This invention is a pump jet nozzle apparatus and consists ofthe novelfeatures herein shown, described and claimed, and this application is asubstitute for my applicatlon Serial Number 719,006, filed June 9, 1924,

and abandoned.

An object is to make a nozzle apparatus having a straight smooth centralflow opening and havin an annular inclined slot or orifice for discarging apower medium into the flow opening, there being an annularchamber from which the slot leads, and means for conducting the powermedium to the chamber.

Another object is to make a power nozzle apparatus which ma be used forpumping li uid out of sumpy lioles and the like, and which may beused'for mixing two fluids together and for various other purposes.

Another object is to make a nozzle having a smooth flow opening fordriven material and an annular angular orifice for discharging drivingmaterial into the driven material so as to move the driven materialthrough the flow o ening.

Other o jects and advantages will appear from the specification anddrawings.

The drawin s illustrate a pump jet nozzle apparatus emgodying theprinciples of my invention and showing the apparatus set up in variousways-for various purposes.

Fig. 2 is a view analogous to Fig. 1 and showing a modification of theconstruction of the pump jet nozzle.

Fig. 3 is a view analogous to Figs. 1 and 2 and showing the nozzle setup with the intake at the top.

Fig. 4 is a fragmentary sectional detail showing the nozzle set uphorizontally.

Fig. 5 is a sectional detail showing a second modified form of thenozzle.

The details of construction and operation shown in the drawings are asfollows:

Referring to Fig. 1, the main frame of the nozzle consists of a lowercasting 1 and an upper casting 2 having internally screw Serial N0.308,536.

threaded nipples 3 and 4 in a straight line. The castings 1 and 2 arefinished upon their meeting faces and are connected together by flanges5 and 6 and bolts 7 inserted through the flanges. In order to break thejoint between the meeting faces of the castings a flange 8 extends 4fromthe casting 1 into a seat in the casting 2. A bell-shaped intake member9 is screwed into the ni ple 3 so as to produce a flaring mouth 10 an astraight passage 11 in line with a straight passage 12 in the casting 1.The lower nozzle member 13 is seated downwardly into the casting 1 andhas a straight central passage 14 in line with the passages 11 and 12and has a beveled outer face 15 leading to the upper end of the passage14. An annular chamber 16 is formed in the casting 1 around the nozzlemember 13. An upper nozzle member 17 is seated in the lower face of thecasting 2 and held in place by screws 18 and has a passage 19 in linewith the passages 11, 12 and 14 and in line with the passage 20 throughthe casting 2.

The lower corner of the second nozzle member 17 is beveled to form aface 21 at the 0pposite side of the annular slot or orifice 22 from theface 15. The bevels of the faces 15 and 21 are divergent from the outletend of the slot 22 downwardly toward the chamber 16 so that the slot 22will be wider at its inlet than at its outlet. An elbow 23 is screwedinto the nipple 4 and has a passage 24 in line with the passages 11, 12,14, 19 and 2O and a discharge pipe 25 is screwed into the elbow 23 andhas a passage 26 communicating with the passa e 24.

It is o special importance that the passages 11, 12, 14, 19, 20, 24 and26 be all of the same size so as to make a smooth passage havf ing noprotuberances or pockets to catch material moving through the passages.

An internally screw threaded nipple 27 is formed integral with thecasting 2 and has a assage 28 leading downwardly to the chamer 16. Apipe 29 which may be of any desired height is screwed into the nipple27, an elbow 30 is screwed upon the pipe 29, and the pipe 31 is screwedinto the elbow 30, there be- 1ng a gate valve 32 incorporated into thepipe 31 and operated by hand lever 33 having a pawl 34 to engage asector 35. A retractile coil spring 36 connects the lever 33 to the pipe31, the tension of the spring being exerted to hold the gate valveclosed.

The pump jet nozzle apparatus thus constructed is mounted in a pit 37which may be a sump hole, a cellar, a basin, or the like, and the pit 37may be filled Awith water, oil and water, mud, slush, or the like, whichwill readily iiow through the outlet passage from the. intake 9.

An desired uidpower such as water or the e, may be supp ied to the pi 31under a desired power or pressure an when the lever 33 is operated toopen the valve 32 a power medium will pass through `the slot 22 andforce the liquid of the pit upwardly and outwardlythrou h thedischargepipe 25. The an le of disc arge of the nozz e 22 relative to te flow opemng may be varied considerably. As shown in the drawings, theface 21 is at an angle of 45 relative to the axis of the flow openingconsidering the passages 11, 12, 14, 19, 20, 24 and so on, and thisangle may be greater or less to suit the conditions under which thenozzle is to be used, the only requirement being that the angle shalldischarge the power medium in the same general direction as thedirection of llow.

It will be seen from Fig. 1 that the fluid supply pipe 31 is at a higherelevation than the situatlon of the nozzle and the discharge pipe 25 andthrough the medium of the controlling valve in t e pipe 31 a means isrovided for controlling the flowing of a uid under a. pressure muchhigher than the hydrostatic head of the liquid to be pum d at theposition of the nozzle. This deve ops a jet of high veloci through thenozzle and elevates the water m the pit 37. The pipe 29 ma be of anysuitable length to give suicient eight to eifect the desired hydraulichead or if necessary suicient pressure may be given by direct pumpnReferring to Athe modi cation shown in Fig. 2, the castings 38 and 39are finished to formthe power medium outlet slot 40 and the castings areconnected by flanges 41 and 42 and bolts 43. Pipe coupling .flanges 44and 45 are formed integral with the castings 38 and 39 and the pipeflange 46 is bolted to the flanges 44 and 45.

AThe pipe line 47 is ta ped horizontally into the pipe flange 46 an thevalve 48mg trols the ilow of power medium through the pipe line 47. Thebellsha d intake member 49 is screwed upon a nipp e projecting from thecasting 38 and the elbow 50 is screwed upon a mpple projecting from thecasting 39, the parts being all arranged and finishedto make a strai htsmooth liow opening 5 1.

Referrin to ig'. 3, the construction 1s substantially t evsame as shownin Fig. 2, except that the nozzle is setbottom upward so that the intakemember 49 is at the top and the outlet pipe includes a pipe 52 connectedto the nozzle, an elbow 53 connected to the discharge end of the pipe52, a pipe 54 connected to the elbow 53, an elbow 55 connected to thepipe 54, and a pipe 56 connectedto the elbow 55, as is necessary to getout of the secondary pit 57. The upper face 58 may be the normal bottomofthe pit and the secondary pit 57 is dug below the level of the bottom58 simply as a place to put the pump jet nozzle apparatus. In operationthis apparatus will discharge all of theliquid above the intake end ofthe nozzle.

This apparatus might be set in a sump hole containing oil and water forthe' purpose of skimming the oil off of the water.

Referring to Fig. 4, the nozzle 59 nny be igs.

the same construction as that shown in 2 and 3, the essential differencebeing that the nozzle is set to have the ilow openin 60 horizontal withthe intake member 61 and the discharge pipe 62 in a straight line.

This construction might be used as a gas burner or oil burner, in whichcase the power medium would be steam or compressed air or gas, and itmay be used for various otherpurposes such as washing a pipe or hose asit is passed through the opening 60.

Referrin to the modied form of nozzle shown in Fig. 5, the internallscrew threaded pipe nipple 63 is formed7 inte al with the lower casting64 which has a aring integral intake. formed upon the cting 64 and a rim66 is formed the casting 67 to screw upon ngen 'the threads y5. Themembers 68 and 69 forming the power medium discharge slot 70 are madesellarate and applied to the cast` so that t ey may be removed and chanas when the become worn or when it is desired to m e the slot 70 largeror smaller by using thinner or thicker members 68 and 69. The width ofthe slot 70 may be adjusted to some extent by screwing the casting 67 upor down relative to the casting 64.

Thus I have produced a pump jet nozzle apparatus having a smooth owopening for driven material and an annular angular oriiice around theiow opening for discharging driving material into the driven material soas to move the driven material through the flow opening.

Various changes may be made without departing from the spirit of theinvention as claimed.
